Before diving into a pool that hasn’t been used for a while, it’s important to prepare it by “shocking” it. This is a necessary step to eliminate any germs and ensure the water is safe for swimming. Shocking involves using strong chemicals, like chlorine, so it’s recommended to wait at least 24 hours after this process before swimming. Jumping in too soon might lead to irritation of the skin, eyes, or even lungs.
Shocking a pool isn’t just a procedure; it’s also a product that helps in this process. The aim is to boost the “free chlorine” levels in the water, which helps destroy unwanted elements like algae and bacteria. Free chlorine is chlorine that hasn’t yet reacted with contaminants in the pool.
The main product used is called calcium hypochlorite, although other chemicals like trichloroisocyanuric acid or potassium dichloroisocyanurate can also be effective for pool shocking.
Generally, it’s advised to wait up to 24 hours post-shock before swimming, based on the pool’s size. You can also test the pH and chlorine levels to know when it’s safe to enter. Chlorine levels should be between 1.0 and 4.0 parts per million, and the pH should range from 7.2 to 7.8.
Swimming in a pool too soon after shocking can cause eye and skin irritation. There’s also a risk of respiratory or digestive issues if you come into contact with these chemicals, so it’s essential to consult a healthcare provider if exposure occurs.
